Fractals and Mandelbrot Set

While mathematics is in itself quite interesting and forms the basis of any modern day research, be it computational biology, machine learning or building complex structure, it can be quite a challenge to decide where to start.  That is why i decided to explore Fractals, thinking of it as a bridge between the nature and science. It brings in some really fascinating concepts which should be good enough for me as a gateway go deeper.  Fractals are in simple language never ending patterns which keep on repeating without an end, because fractals are never ending they have an infinite perimeter but finite area.  Since the patterns repeats indefinitely but if you draw a circle around the peremeter the area will remain finite.  It is like adding 1+0.1+0.01+0.001 and never making 2 This video explains the basic concept really well  Fractals are found everywhere nature in Trees, Rivers, Branching patterns, Hurricanes and Galaxies. It tries to bring order and understandin...

When I landed McCarran International Airport, the first surprise for me was the...
